IMPROVEIME'NTIN FASTENERS FOR THE MEETING-RAILS 0F SASHES.

Specification forming part of Letters Patent No. [71,694, dated January4, 1876; application filed December 4, 1875.

CASE B.

' To all whom it may concern:

Be it known that I, JOSEPH R. PAYSON, of Chicago, in the county of (lookand State of Illinois, have invented a new and useful Improvement inWindow-Sash Look, of which the following is a specification:

Figure 1 is a top view of my improved sashlock, shown as attached to thesash and unfastened. Fig. 2 is the same view as Fig. 1, but showing thelock fastened. Fig. 3 is a side view of the same, the meeting-railsbeing shown in section through the line w at, Fig. 2.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish an improved sash-lock to beattached to the meeting-rails of the sash, which shall be simple plateand its flange; in the locking arm and hook, in combination with theplate and its flange, and with the plate and its pin; and in a sash-lookin which the locking-arm is pivoted at or nearly at an angle offorty-five degrees with the length of the meeting-rails of the sash, ashereinafter fully described.

A represents the meeting or top rail of the lower sash, and B representsthe meeting or bottom rail of the upper sash. O is a plate, secured tothe rail B, and which is provided with an upwardly-projecting flange orlug, (3, formed at an angle of about'forty-five degrees with the lengthof the forward edge of said plate, and having a hole formed transverselythrough its middle part to receive the pivoted ward side, when in theposition shown in Fig.

1, made straight, so as to be close to and parallel with the forwardedge of the plate 0 and rail B. The outer end of the arm D has a hook, dformed upon it, and is provided with a thumb-piece, d for convenience inoperating it.

By this construction, when the arm D is turned upon its pivot throughone-half of a revolution, its outer part will rest upon and be at rightangles with the meeting-rail A of the lower sash.

Upon the part of the arm D that bears upon the edge of the rail A isformed a lip, d", so that the bearing or point of contact may be closeto said edge. To the upper side of the rail A, directly opposite theplate 0, is attached a plate, E, for the arm D to rest upon, to preventthe sash rail from being worn. Upon the outer part of the plate E isformed an upwardly-projecting pin, 6, the forward side of the upper partof which is beveled oif, as shown in Figs. 1, 2, and 3.

When the arm D is turned down upon the rail A the hook d passes over thepin 6, and the bevel of said pin draws the rails A B together, so thatit will be impossible to insert any instrument between the sash-rails totamper with the fastening. The pin 0 and hook d also assist the arm D inresisting any attempt to open the sashes. When the arm D is turned downinto the position shown in Fig. 2 any attempt to lower the upper sash orraise the lower sash will press against'the arm D below its axis, and atsuch an angle with said axis as will tend to turn the arm D downward,causing it to hold more firmly. The same effect would be produced by anyinstrument inserted between the rails A B.

By taking hold of the thumb-piece d the arm D may be easily turned tolock and unlock the sashes.

With this look the operation of turning the arm D in fastening thewindow will draw the lower sash up or the upper sash down, should theynot be fully closed, without its being necessary to fully close saidsashes with the hand before operating the lock.

Having thus described my invention, 1 claim as new, and desire to secureby Letters Patent- 1 The locking-arm D, in combination with thelplate O,and lug on flange a, substantially l as herein shown and described.

2. The locking-arm D and hook 11 in combination with theplate O and itsflange c, and

with the plate E and its pin e, substantially as herein shown anddescribed.

3. A sash-lock in which the locking-arm is JOSEPH R. PAYSON.
